+Subject: [PATCH 24/40] Xi: unvalidated lengths in Xinput extension
+ [CVE-2014-8095]
+
+Multiple functions in the Xinput extension handling of requests from
+clients failed to check that the length of the request sent by the
+client was large enough to perform all the required operations and
+thus could read or write to memory outside the bounds of the request
+buffer.
+
+This commit includes the creation of a new REQUEST_AT_LEAST_EXTRA_SIZE
+macro in include/dix.h for the common case of needing to ensure a
+request is large enough to include both the request itself and a
+minimum amount of extra data following the request header.
+
+v2: backport to nx-libs 3.6.x (Mike DePaulo)
